Seminole Canyon State Park and Historic Site in Val Verde County, west of Comstock, contains 2172.5 acres; the park was acquired by purchase from private owners in 1973 - 1977 and opened in February 1980.

Diverse flora and fauna throughout the park include white-tailed deer, raccoons, armadillos, and squirrels. There is sparse vegetation, the terrain is rocky, and there are deep canyons.

Early man first visited this area 12,000 years ago, a time when now-extinct species of elephant, camel, bison, and horse roamed the landscape. The climate at that time was more moderate than today and supported a more lush vegetation that included pine, juniper, and oak woodlands in the canyons, with luxuriant grasslands on the uplands. These early people developed a hunting culture based upon large mammals, such as the mammoth and bison. No known evidence exists that these first inhabitants produced any rock paintings.

By 7000 years ago, the region had undergone a climatic change that produced a landscape much like today's. A new culture appeared in this changed environment. These people were increasingly dependent on gathering wild plants and hunting small animals and less dependent on hunting big game. They lived in small groups since the land would not support larger social units for long periods.

Despite the struggle for survival, some of these prehistoric people found the creative energy to paint the pictographs found in Fate Bell and other rock shelters of the Lower Pecos River Country. The distribution of this distinct style is limited to a district which includes a portion of the Rio Grande, Pecos, and Devils River. More than 200 pictograph sites are known to contain examples of their style of rock paintings ranging from single paintings to caves containing panels of art hundreds of feet long. Although numerous figures or motifs are repeated in different locations, the exact meaning of the paintings is buried with the people who painted them.

The first known European in this area was Castano de Sosa, who set out from Monciova Mexico, in 1590 and traversed much of present Val Verde County en route to New Mexico. The U. S. Army was the first American presence in the Lower Pecos. In 1851, Lieutenant Nathaniel Michler made a reconnaissance of the Rio Grande above and below its junction with the Pecos for the United States and Mexico Boundary Commission. After the Civil War, Lieutenant Bullis and his Seminole-Negro scouts operated in the area, and Bullis blasted a wagon road into the Pecos Canyon near the Rio Grande to provide the military with a shorter route between Forts Clark and Davis.

In 1882, construction of the Southern Pacific Railroad reached the present park location. The route to connect El Paso with San Antonio was begun after the merger of the Galveston, Harrisburg, and San Antonio Railroads with the Southern Pacific. The section of railroad in the canyon of the Rio Grande was finally abandoned in 1892, when a new bridge spanning the entire breadth of the Pecos River Canyon was completed. The present bridge was built at the same site during World War II.
